  • 21:9 Curved LCD

  • 3000:1 Contrast Ratio
  • 300 cd/m² Brightness

    The CJ791 features two Thunderbolt 3 ports to connect compatible Macs and PCs. Thunderbolt 3 transmits video and data at speeds of up to 40Gbps — 8 times faster than USB 3.0 — and simultaneously charges devices (up to 85W), all over a single cable.

    Multiple Inputs

    With two Thunderbolt 3 ports as well as DP, HDMI and USB inputs, the CJ791 provides multiple connection options for PCs, consoles, and external devices. The built-in 7-watt stereo speakers offer an enhanced entertainment experience when viewing videos and playing games.

    34" Ultra-Wide Screen

    The 34’’ ultra-wide curved display with its 21:9 aspect ratio provides all the workspace you need to multi-task efficiently and in comfort. Forget about inconvenient dual monitor set ups and experience truly seamless multitasking on a single screen.

    Curved for Comfort

    The curved screen is engineered to follow the natural curve of your eyes for a more immersive and comfortable viewing experience.

    PBP and PIP

    Picture-by-Picture (PBP) lets you display to two sources onscreen at their native resolution. Optimize your multi-tasking further with Picture-in-Picture (PIP), which lets you resize the second source to up to 25% of the screen and position it anywhere.

    Quantum Dot Color

    Supporting up to 125% sRGB color space, Quantum Dot technology delivers colors that are brighter, crisper, and more natural — especially reds and greens. Every monitor is factory-calibrated to ensure the most accurate and life-like images.

    3000:1 Contrast Ratio

    Samsung’s VA panel technology provides a 3000:1 contrast ratio that delivers deep blacks, brilliant whites, and rich colors for clear, vibrant images.

    AMD FreeSync

    AMD FreeSync synchronizes the refresh rates of your graphics card and the CJ791 to minimize image tearing and stutter. The smoother transition between image frames provides seamless gameplay and video playback for uninterrupted viewing.

    Fast 100Hz Refresh Rate

    The fast 100Hz screen refresh rate provides smoother, silkier mouse sensitivity for enhanced productivity in any application. It also reduces screen stutter in fast-moving action scenes for a flawless gaming experience.

    Stylish Design

    The CJ791’s curved screen and three-sided bezel-free design, along with its glossy-white rear panel that neatly conceals cables, creates a slim and striking profile that is the perfect complement to any Thunderbolt 3 Mac or PC.
